Option 2 : Malini needs one more sea shell to complete 11 necklaces

Given:

Number of seashells Malini collected = 200

Number of broken shells = 3

Number of shell left with her = 200 - 3 = 197

Number of seashells in a necklace = 18

Calculation:

To solve this question we have to check all the options:

Option 1) Malini can make 11 necklaces with the seashells.

⇒ 11 necklaces = 11 × 18 = 198 ( incorrect )

Option 2) Malini needs one more seashell to complete 11 necklaces

⇒ 11 × 18 = 198, and she has 197 seashells, so she needs one more seashell to complete 18 seashells ( correct ).

Option 3) Malini can make 10 necklaces and she would leave with 15 seashells.

⇒ 10 × 18 = 180, remaining sea shell = 197 - 180 = 17 ( incorrect )

Option 4) Malini can make 12 necklaces with the seashells.

⇒ 12 × 18 = 216 ( incorrect )

So, option 2 is correct.
